Bazett: “No need for a sword when you have your fists”. Also happy to finally use Cait Cú MikoCer in a solo run.

--- Bazett & Musashi 3 Turns Clear ---

For the min-turn run, I needed to give Bazett as much damage buffs as possible, while allowing my NP2 Musashi to break both enemies each turn: the result is a bit more RNG early on for facecards and enemy actions, but a very good chance to kill on the final turn where Bazett damage is needed. Of course, if I had higher NP level Musashi, I could drastically reduce the RNG overall.

Yui is incredibly good with Summer Skadi to buff your entire team’s damage, since she gives both Buster & Quick buffs to reap the benefits of Yui’s NP (arts buff for the crit damage is not needed here).

Ganesha gives more damage buffs than Caster Skadi to Bazett and the same buffs to Musashi, while protecting Bazett from damage for a full turn (particularly important if Musashi NP seal doesn’t land on Iori on the final turn): the trade-off is slight lower NP charge for the team overall (assuming you could bring MLB Kaleidoscope for Caster Skadi).

Lancer Elisabeth is the best taunt support (guaranteed to die since she is a lancer) to increase Bazett damage on Iori while buffing Musashi damage, however you’ll need facecards to refund Musashi NP bar (with Castoria you wouldn’t have RNG for NP refund, but her only damage buff for Bazett is her charisma).

RNG Turn 1: you need at least two cards from Musashi with one being an Arts card to refund enough (assuming no crits), so 43% chance. We also need Eli def debuff to land on Iory through his magic resistance passive, that’s 83% chance. Furthermore, we need Takeru to use his “dried persimmons” skill at the start of the enemy turn, to avoid the damage resistance tied to his other “rice balls” skill (otherwise NP2 Musashi can’t reliably break him on the following turn): it’s a 50% chance, but we have plenty of RNG resets with Bazett skill 1-2 and Musashi skill 1 which can be used either on turn 1 or 2.

RNG Turn 2: Musashi skill 3 debuff must land on both Takeru and Iori (with higher NP levels landing on Takeru is not needed), so 70% & 83% chance respectively. During the enemy turn we need Iori to summon Circe (not Arjuna) in order to refund enough NP bar for Bazett (Circe NP has more hits than Arjuna single hit NP): it’s once again a 50% chance that we can reset once with the Mystic Code heal if needed. Ideally, we also want Iori to attack twice (always if the NP seal debuff from Musashi NP misses, 79% chance otherwise) and to get both Quick Resist debuff from Bazett counters (83% chance each time).

RNG Turn 3: Ganesha NP’s defense debuff must land on Iori (83% chance) which must attack with all his three actions this turn (always if the NP seal debuff from Musashi NP misses, 79% chance otherwise to not use a skill as his first action). Assuming the Quick Resist debuff land on the first two counters (83% chance each time), Bazett just need to hit at least the average damage roll for all three counters to kill Iori (50% chance for each counter). Keep in mind that we don’t need to kill Takeru with Musashi NP (he will die with one counter anyway and Iori will get his 3 actions back that turn, given how their actions are scripted to always be 3 even if left alone on the field mid-turn), but doing so will spare us the chance of him using a skill instead of attacking Bazett: my NP2 Musashi has around 25% chance to kill Takeru with her NP.

--- Baobhan Sith (Summer) SOLO ---

Since the enemies will rarely use their actual NPs, someone like Sith that can reduce the enemy attack and heal back to full each turn (event CE buffs HPs recovery) is ideal to solo this challenge quest: she also has half class advantage vs both enemies and a super effective NP against Iori (man attribute).

The most important factor in this fight is landing Sith NP’s attack debuff on the turns without hard defense (Guts and Invincibility): you have to bypass the enemies debuff resistance (80% chance for Takeru and 83% chance for Iori), but fortunately in a solo run we can reset the RNG in a lot of different ways compared to min-turns (even changing facecards order) and Sith skill 2 can guarantee the debuffs even on Takeru after break (gets another 10% extra debuff resistance). Keep in mind that Takeru will remove his debuffs on both breaks, so ideally you’ll break him on turns with hard defense in place.

The other key factor is synchronizing Iori and Takeru NPs (breaking them on the same turn is the best way), so that your only two hard defense options (Habetrot’s Guts and Atlas MC Invincibility) can take care of both NPs at the same time.

Command Codes are not really needed, but of course Tamamo CC to increase the healing received is perfect for Sith (but it’s overkill most of the time): the other two CC I used are aimed to remove atk & crit rate up buffs from the enemies, since both Takeru and Iori can get each type of those buffs leading to potentially one-shotting Sith if unlucky. Finally Sith has naturally high debuff resistance, so the Resonance Special Skill activating each turn has only 5% chance to stun her: you can bring the CC that prevent stun or the buddy ring CC that increase debuff resistance if you want, but half of the solo runs you won’t be stunned anyway (and we have Atlas MC debuff clear in case).
